LFhĂŠangles ofa quadrilateral are in the ratio 1 :2:34. Find the smallest and the largest angle

Answer»

Let the angles of quadrilateral are x, 2x, 3x, 4x

Sum of all angles of quadrilateral = 360

Then,x + 2x + 3x + 4x = 36010x = 360x = 36

Angles of quadrilateral are36, 72, 108, 144

Therefore smallest angle = 36largest angle = 144

Recall, is defined as the ratio of the circumference (say c) of a circle to its diameter(say d). That is, π--. This seems to contradict the fact that π is irrational. How willyou resolve this contradiction?

Answer»

There is no contradiction. When we measure a length with scale orany other instrument, we only obtain an approximate rational value.We never obtain an exact value. For this reason, we may not realisethat eithercordis irrational. Therefore, thefractionc/d is irrational. Hence, π is irrational.

(3) Observethe following figure. If thesome current be induced in the coil B? Explain.current in the coil A is changed, will

Answer»

It is because when the current in your coil A is successfully changed, then the magnetic field linked with it also changes.

Hence, the overall magnetic field around the coil B also alters.

This kind of change in the magnetic field the lines around coil B actually induces the electric current in this field.

It is known as electromagnetic induction.

e lirst ree lens.How many 3-digit numbers are divisible by 7 ?

Answer»

first = 105last = 994so , Tn = a+(n-1)dHere , 994 =105+(n-1)7or , 7(n-1)=994-105or , 7(n-1)=889or , n-1=127or , n=128 .

3 digit no are 100 to 999a= 104d=7ln=994let n be the term a+(n-1)d=on104+(n-1)×7=9947n-7=994-104=8897n= 889+7=896n= 896/7=128total no of term = 128

Numbers begin from 105 ....... 994

here a= 105l= 994n=?d= 7so994 = 105+(n-1) 7= 105+7n-7994= 98+7n994-98 = 7n896/7 = nn= 128

So , 128 three digit numbers are divisible by 7

Least 3 digit number divisible by 7 is 105The biggest 3 digit number divisible by 7 is 994

Sn= a+(n-1)d=>994= 105+(n-1)7=>7(n-1)= 889 {994-105=889}=>n-1= 127=> n=128...

The first number =105,last number=994,last term= a+(n-1)d,994=105+(n-1)7,889=(n-1)7,127=n-1,n=126

10. PQRS is a parallelogram. T is the midpointof PQ (Fig. 11.18). ST bisects ZS. Provethata) QR = QT b) RT bisects ZRc) ZSTR = 90°Fig. 11.18

Answer»

We have,PQRS as the given parallelogram, then PQ∥RS and PS∥QR.Since PQ∥RS and TS is a transversal, then∠PTS = ∠TSR (Alternate interior angles) .

....(1)Now, TS bisects ∠S, then∠PST = ∠TSR ........(2)From (1) and (2), we get∠PTS = ∠PSTIn

∆PTS,∠PTS = ∠PST (Proved above)

⇒PS = PT [Sides opposite to equal angles are equal] .........(3)

But PS = QR (opposite sides of parallelogram are equal) ........(4)

PT = TQ (As T is the mid point of PQ) ..........(5)

From (3),(4) and (5),

we getQR = TQIn ∆TQR,QR = TQ

(Proved above)⇒∠QTR = ∠QRT [angles opposite to equal sides are equal] .........

(6)Since PQ∥RS and TR is a transversal, then∠TRS = ∠QTR (Alternate interior angles) .........(7)

From (6) and (7),

we get∠QRT = ∠TRS⇒TR bisects ∠R.

Now, ∠R + ∠S = 180° [Adjacent angles of ∥gm are supplementary]

⇒12∠R + 12∠S =90°⇒∠TRS + ∠TSR = 90° .......(8)I

In ∆TSR,∠TRS + ∠TSR + ∠RTS = 180° [Angle sum property]⇒90° + ∠RTS = 180°⇒∠RTS = 90°
